similar to: Hyperthreading?

That's the problem we had with Asterisk and HT on a 2.4 Kernel: whenever Asterisk was staying in the RTP stream, and HT was enabled (on a Dell Dual Xeon system), we had choppy audio. After disabling HT, everything was fine again. Nothing measurable, indeed, but you could definitely hear it. So there *must* be something. -Manuel -----Messaggio originale----- Da: Peter Corlett

Hello, I read an interesting article on 2cpu.com that talks about the performance differences between a P4 processor with Hyperthreading(HT) enabled and disabled. http://www.2cpu.com/articles/ht_explored/index.html The bottom line of the article is that processor intensive applications greatly benefit from HT being enabled, but memory intensive applications can actually see a slight decrease in

My Dell 2800 Dual 64bit Proc. machine came in with hyperthreading enabled. (they call it virtual processor??) I have been intending for a month to disable it. Tonight, I rebooted, turned it off, and let the system come up. zaptel loaded and asterisk loaded, but both of my t1s were red. (it is a TE411P) /proc/interrupts looked OK, zttest gave OK numbers. I doublechecked all of the files in case

Hi, I can''t get rid of an annoying domU machines hanging issue with Hyperthreading enabled in my BIOS. Hardware config: IBM x325 series 2 * CPUs Intel Xeon 3.06 Ghz Xen version: 3.0.0 Kernel version: 2.6.12.6 Linux distrib: Debian Sarge 3.1 r1 I run 1 domU machine on my dom0, here is my Xen config: . xen0: /etc/xen/xend-config.sxp : (dom0-num-cpus 0) .

Hi, I have been trying to get Hyperthreading to work in a Windows HVM on Xen 4.1.2 as described in ''xmexample.hvm''. I think I have set it up correctly, but I can''t seem to get it to work. There is not much documentation on it and most topics are from years ago. I''m curious to know to whether this functionality is still supposed to work. I''m aware that

Just gave 3.0 a spin. Had been running 2.0.7 for the past 3 months or so without problems (aside from intermittent failure during live migration). Anyway, 3.0 seems to have an issue with my machine. It starts up the 4 domains that I''ve got defined (was running 6 user domains with 2.0.7, but two of those were running 2.4 kernels which I can''t seem to build with Xen 3.0 yet, and

I just tried to install CentOS (x86_64 4.4 and i386 4.3, not both at once, when I found the 64bit version didn't boot, I tried the 32bit version, same result) on a dual Naconda Xeon system. I get an OOPS just after the IDE info is printed on the screen during boot (this is booting off the CD during the install phase). After mucking about with the bios settings (and many reboots later), I

Hi, All: Does the guest OS need to detect hyperthreading? One would think that the hypervisor decides what to schedule on what CPU, and the job of the guest is not to be too smart for its own good. So, my first reaction was to comment detect_ht() altogether. Fedora Core 5 has the code in detect_ht(), though I have no idea what the results of this are on HT CPUs, if they match the reality.

Hi the number of cpu cores that you see with top times 512Mbyte is the level of ram that's needed e.g. a hp-gen8 with 2 octo

Another question some of you may help me make decisions on. I've been doing some reading that indicates that having HT turned on in this dual xeon machine might actually slow down the computing process rather than speeding it up. I rebooted this a.m., and turned HT off, just prior to my main application run. One thing that might be of note, this application is using OMP for utilizing

Hi, Has anyone had success using a TE410P card in an HP-Compaq DL380 G4 server? For me the card is detected fine, but the system just never sees an interrupt from the card. I've tried everything I can think of. The card definitely works. Its Fedora Core, but we also tried a stock 2.6.10 kernel. We tried with and without Hyperthreading, with "noapic", we disabled all the

Hi, I am having some problems mentioned below, the box is in production live environment with traffic around 30 - 100 calls. I am running T/E410P in a Dual P4 xeon with HT disabled. I am using zaptel 0.9.0 and asterisk stable 1 release. There is no gui, just mysql, perl (small script) and asterisk. System runs very smoothly if the calls are around 40-50 and comes one by one , however sometimes

Chip Clock HT Cache Bus Speed --------------------------------------------------------- 5080 3.7 GHz YES 2MB 1066 MHz 5160 3.0 GHz NO 4MB 1333 MHz Does the .7 GHz and HT worth more then 4MB cache and higher bus speed? The application is VoIP so there is not a lot of IO so I would not think Bus Speed would matter. I am finding mixed information on HT, some say it is great, others say it

Hi, Anyone know how to compile asterisk for a hyperthreaded processor? Thnx

Hi, my video sharing website (politube.org) that I developed with rails, runs on lighttpd/fcgi (I know it is obsolete by now) and is severely under load and regularly blocks because the lighttpd process chews up 50% of RAM (1GB). So now I want to move the system to a new server with 8GB, 64bit , Quad core processor (intel i7 920) but I am not sure if hyperthreading will really do anything better.

I have some beefy dual-Xeon servers that I will be using for Asterisk VoIP applications (i.e. no Zaptel cards). Using 2.6.11-1.14_FC3smp as the kernel (Fedora Core 3), and currently with Asterisk STABLE. My question is concerning the CPU setup, as I've seen conflicting or out-of-date suggestions: given the above config, should I have hyper-threading turned on or off? Turned on appears like 4

I've to setup Asterisk on a Dell PowerEdge 1750 server. Its dual Xeon 3GHz with Hyperthreading. People on this list who have experience with this server please advise me how is the performance of Asterisk on this server, what flavour of linux is good on it etc. Is Hyperthreading going to be a problem or not. I once read somewhere that hyperthreading caused some voice quality problems in
